I have a new PC and set up. I have (stupidly, not knowing what I was doing) changed from an Administrator to a Standard User. There are NO other Administrators set up on this PC! Now, there seems to be NO way to change back from Standard user to Administrator. Every solution I have come across needs an Administrator password and of course, I don;t have one because I am not signed in as an administrator! Does anyone know of a workable solution to this? I can't even do a system restore because of course, I need to be signed in as an Administrator! ANY assistance will be most gratefully received!
